Prefabricated Thermocouple
Product Brief Introduction:
Industrial prefabricated thermocouples act as the quintessential sensors for measuring temperaturetemperature often paired with display units, recording instruments and electric regulators. These thermocouples can directly measure the temperature of liquids, steam, gas mediums, and solid surfaces within a range of 0°C to2300°C across various industrial processes.
Features:
Easy assembly,hassle-free replacement,
Pressure-spring type temperature sensors with excellent anti-vibration properties,
large measuring range,
high mechanical strength, and robust pressure resistance.
Armored Thermocouple
Product Brief Introduction:
Armored thermocouples offer the distinct advantages
o
f flexibility, high-pressure resistance, and rapid thermal
response time, making them both sturdy and durable. Much like fabricated
t
hermocouples, these sensors measure temperature
and are often used with display instruments, recording
instruments, and electronic
regulators. Additionally, they can serve as temperature sensing elements for
assembled
thermocouples, capable of measuring temperatures in liquids,
steam, gas mediums, and solid surfaces within a range of 0°C to 1300°C across various production
processes.
Features:
Short thermal response time helps minimize dynamic
tolerance,
flexible installation and
usage,
large measuring range,
high mechanical strength, and robust pressure resistance.
Explosion-Proof Thermocouples
Product Brief Introduction:
Designed for use with display instruments, recording
instruments, and electric computers, these thermocouples provide direct temperature measurement for liquids, steam, gas mediums, and solid surfaces within a range of 0°C to 1300°C, particularly in environments containing
hydrocarbons and other explosives.
Features:
Multiple explosion-proof types ensure superior explosion-proof performance.
Featuring pressure spring sensing elements, our sensor exhibits exceptional vibration resistance, ensuring reliable performance in demanding environments.
With a vast measuring range, this sensor is designed to accommodate a wide variety of industrial temperature monitoring needs.
Boasting high mechanical strength and excellent pressure resistance, this sensor is built to withstand the toughest industrial conditions.
